Application filed. February 4, 1922. Serial No. 534,062.

To all whom it may concern Be it known that 1, DANKEL J. BUTTER- risiin, a citizen of the United States,'residing at Les Angeles, in the county of Los' Angeles and State of California, have invented certain new and useful Improvements in Check-Controlled Apparatus, of which the following is a specification, reterence being had therein to the accompany ing drawings.

This invention relates to a check-coir trolled apparatus, and the object of the invention is the construction of an etiicicnt and durable machine, the operation of which is controlled by the insertion of coin, which machine will dispense liquid into receptacle upon the placing of a coin in the machine.

This application is a continuation in part of my original application, Serial No. 421,- 393, which has matured into Patent No. 1,407 ,838.

With the foregoing and other objects in view, my invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter de scribed, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a vertical, sectional view, taken on line 1-1, Fig. 2, and looking in the direction of the arrows.

Figure 2 isa vertical, sectional view,

taken on line 2 2, Fig. 1, and looking in the direction of the arrows.

Referring to the drawings by numerals,

1 designates the casing which includes the front section 2, the central section 3, and the rear section 1. In the front section 2 is formed an upper coin slot 5, at the bottom of which is a compartment 6, that communicates with the lower coin slot 7; the lower coin slot 7 opens into the compartment or receptacle 8. Adjacent to the upper coin slot 5 is a compartment 9, Fig. 1, in which compartment is mounted lever 19. Lever 10 is pivotally supported at 11, within compartment 9. Lever 10 has a coil spring 12 hearing against the same for holding the lever out in the path of movement ot a coin 13, Fig. 1. lVhen the coin 13 is placed in slot 5, the weight of the coin is suiiicient to overcome the outward pressure of spring 12, resulting in the lever 10 being pushed inwardly as the coin travels to its lowest position within the upper coin slot and into the compartment 0. The lower end 01? lever 10 is enlarged, at 1%, and on one side of this enlarged portion lat are a pair of pins 15. The cog 16 is rotatably mounted in the compartment 9 and the teeth 01'' the cog 16 engage the pins 15, oil lever 10; also, said teeth engage cups or receptacles 1'? in the compartment 18. One tooth of each cog 16 only engages cup 17, and when the lever 10 is pushed inwardly, by the coin 13, the tooth that is engaging a cup willslightly raise the cup until the tooth passes the edge or" the cup and then the cup will drop down and out of the compartment 18 and the next cup will fall against a tooth of the cog 16 and will not be discharged until another coin has been dropped into the slot 5. The lowe'rpin on the lever 10 operates or rotates the cog, while the upper pin acts as a stop or hralte for limiting rotary movement 01 the cog each time the coin 13 is dropped in the slot 5.

A primary valve 19 is positioned in the central section 3 of easing 1, and an auxil iary valve 20 is positioned in the rear section 4, The primary valve 19 is operated by a coin-controlled pusher device; this coin-controlled pusher device comprises a manually-operated outer section 21 and an inner section 22. The outer section 21 includes the push cap 23, pin 24* and spring 25. i

A stem 27 is provided for the valve .19 and is provided at its outer end with a head 26. A spring :28 is provided about this stem .27 and normally holds the stem in the position shown in Figure 2 with the valve 19 in the closing position against the seat 29 and the cross slot 26 of the head at registering with the coin chute 5. It will therefore be seen that when a coin is placed in the chute and rests upon the abutment 5 this coin will extend into the slot 29 and engage the strip 26*. will therefore be moved upon the pivot pin at its upper end against the action 01 the spring 26 and will extend across the pocket 39 so that when the cap s3 is moved inwardly the pin 2 will engage the strip and move the stem 27 inwarc'ily to move the valve 19 to an open position. lVhen the stem 2'? and head 26 are moved in wardly the coin will he moved oil of the abutn'ient and will drop into the coin box The strip 26 but the strip 26 Will not return. to its normal position until pressure upon the cap 23 is removed.

The auxiliary valve device 21- is operated by liquid pressure, the inner end of pin 27 engaging the same; this valve device 2 1 comprises shaft orpin 31, provided with valve 20, and on the inner end of pin 31 is a plunger head or cap 32 against which the inner end of pin 27 engages. When the valve device 2st ismoved toward the outer end of section 4, the valve will be unseated, permitting Water or carbonated water to enter therear end 33 of the casing 1, passing fromsection at into by-pass 34 (dotted lines, butmore. fully disclosed in my original application, Serial No. 421,393)

and discharges into nozzle 35.

The sirup receptacle 36, preferably formed of transparent material, such as glass, is mounted upon the casing 1 and cornniunicates with the interior thereof. The valve device 37 is mounted upon the receptacle 36for permitting air to pass from within the receptacle assirup or liquid fills the same. Sirup is supplied to the receptacle 1 by supply pipe 38.

It is to be understood that the spring 28, as well as spring 38 normally retains the valves 19 and 20 in a closed or seated posi tion tor preventing liquid passing through the casing until a coin has been dropped in the machine; upon a coin being dropped in the machine, the manually-operated pusher device 21 can be forced inwardly to move the primary. valve 19 to an open position (see dotted lines, Fig. 2), and when the device is inthe position shown dotted lines, itwill closenthe inner endofsupply pipe 38, preventing any more sirup being diss charged into the section. 3 and receptacle 86, while the sirup is being discharged from receptacle, 36 through nozzle The supply ipe 38 .norma1lykeeps the receptacle 36 filled.

The inward movement of valve 19, from its seated position, will result in the inner end of pin 2': pushing against the plunger head or cap 32, torclng it inward, causing the auxiliary valve 20 to move to an 1 19 'is moved to its innermost position, as

shown by dotted lines (Fig. 2) sirup will momentarily be prevented from entering[ the casing 1 through pipe 38, but upon the return of valve 19 to its seated position, sirup can flow through pipe 38 and fill the receptacle 36.

Further reference may be had to the drawings and specification in my corpending, original application, Serial No. 421,393.

What I claim is:

In a structure of the character described, a casing, a coin chute intersecting said casing, dispensing means including a spring pressed inner plunger having a head at its outer end provided with a transversely eX- tending slotnormally registering .with the coin chute, the head having a pocket extending axially of the plunger, a strip movably mounted in the slot and adapted to be engaged by a coin placed in the chute and be moved to extend across the pocket, an outer actuating plunger spring held against inward movement and slidable into the pocket and adapted to impart movement to the inner plunger when a coin is positioned in the slot and the strip moved across the pocket and engaged by the inner end of the outerplunger, and an abutment in the coin chute for supporting the coin until the inner plunger is moved inwardly by the outer plunger.

In testimony whereof I hereunto affix my signature.
